LOW EMISSIVITY COATING FOR PREVENTING INFRARED RADIATION LOSS AND THE METHOD OF MANUFACTURING THE SAME

摘要

PURPOSE: A method for manufacturing a low-emissivity coating film for preventing the loss of infrared radiation is provided to show excellent durability and low emissivity, which results from an oxide layer coated on the coating film. CONSTITUTION: A method for manufacturing a low-emissivity coating film for preventing the loss of infrared radiation comprises a step of coating a first metal oxide layer on a metal substrate. The first metal oxide layer is composed of metal oxides. The low-emissivity coating film shows low emissivity and high heat resistance. The metal substrate comprises one kind of metal or an alloy consisting of one or more kinds of metals, which show no deformation even at 300°C or higher. The first metal oxide layer and second metal oxide layer contain one or more materials selected from the group consisting of ATO, ZnO, ITO, SnO2 and MgO.
